Dog Limping: Logging Onset, Severity, and Pattern

When a dog starts limping, the instinct is to call the vet immediately. Sometimes that's right. But quite often what a vet needs first is a clear account of what's actually happening - and by the time you're in the consulting room with a dog who's now walking normally, that account is harder to give than you'd expect.

Limping in dogs is described clinically as lameness, and the details of that lameness - which leg, when it's worse, whether it appeared suddenly or gradually, whether it's improving or worsening - are genuinely diagnostic. Different conditions produce different patterns, and the pattern is often the first clue. The PDSA PAW Mini Report 2025 noted that 25% of UK vets ranked obesity among the top five welfare concerns for dogs specifically because of its association with joint disease - making weight a relevant factor in many limping cases, particularly in middle-aged and older dogs.

Sudden onset vs gradual onset

This distinction matters a lot.

Sudden-onset lameness - your dog was fine this morning and is now clearly not weight-bearing on one leg - is usually injury. A cut or thorn in the paw pad, a sprain or strain from jumping awkwardly, a broken nail, a bee sting. It can also indicate something more serious, like a fracture or cruciate ligament rupture. The sudden nature and severity guide how urgently you respond.

Gradual-onset lameness - your dog has seemed slightly stiff getting up for the last few weeks, and now you're noticing a visible limp - is usually degenerative. Arthritis, hip dysplasia, elbow dysplasia, or other joint conditions build over time and become apparent when the compensating mechanisms stop being enough.

The difference in urgency is significant: a dog who can't bear weight on a leg that was normal this morning needs to be seen today. A dog who's been gradually stiffening over two months needs to be seen soon, but probably not as an emergency.

Which leg, and when is it worst

Log which leg is affected. If it's a front leg, note whether it's the whole leg or whether the dog is specifically favouring one area - shoulder, elbow, wrist, paw. Same for back legs: hip, stifle (knee), hock, paw.

Worse after rest, better with movement is the pattern typical of arthritis. These dogs are often stiffest first thing in the morning or after a long nap, and they "warm out of it" once they've been moving for a few minutes.

Worse with exercise, better after rest suggests soft tissue injury or inflammation. The dog is fine until they've been running around, then starts to limp.

Intermittent skipping - a few strides of three-legged movement, then back to normal - is classic for luxating patella (slipping kneecap) in small dogs. It can look alarming but often resolves on its own in mild cases.

Log which pattern you're seeing, because when you arrive at the vet and the dog is walking normally, "it's worse after she's been lying down for a while but gets better once we're moving" is the information that steers the examination.

What to examine at home

Before calling the vet, check the affected leg for obvious causes:

• Paw pad: cuts, thorns, foreign objects embedded in the pad or between the toes, cracking
• Nails: broken nail (including the quick), nail growing into the pad
• Swelling: any visible swelling compared to the same limb on the other side
• Heat: does the limb feel warm compared to the other?
• Wounds: any cuts, bite marks, or injuries on the leg

If you find a thorn or foreign object, remove it carefully if you can. If the wound is deep or the dog is in significant pain, leave it for the vet.

Log what you found, or didn't find. "I checked the paw thoroughly and there's nothing visible" is useful information.

When to go straight to the vet

• Non-weight-bearing on a limb (holding it up completely)
• Visible bone deformity or swelling
• An injury you witnessed - a fall, a road traffic accident, a collision
• Acute pain on handling the limb - yelping, snapping, excessive trembling
• Limping alongside other symptoms - lethargy, not eating, fever

For a dog who's limping but still weight-bearing and otherwise comfortable, a same-day or next-day appointment is usually appropriate. Call your vet and describe what you're seeing - they'll advise on urgency.

Breed considerations

The most common causes of limping each have dedicated condition guides: hip dysplasia, arthritis, cruciate ligament disease, elbow dysplasia, luxating patella, and IVDD.

The BVA (British Veterinary Association) runs breed health screening schemes specifically for hip dysplasia, elbow dysplasia, and other inherited orthopaedic conditions - results of which are held in centralised databases and can be useful context when a breed-predisposed dog presents with lameness. Some breeds are predisposed to specific conditions, which influences what a vet will consider first:

Labradors, Golden Retrievers, German Shepherds: hip dysplasia, elbow dysplasia, cruciate ligament rupture

Dachshunds: intervertebral disc disease (affecting the spine, causing apparent hindlimb weakness or dragging rather than traditional lameness)

Small breeds (Chihuahuas, Yorkshire Terriers, Pomeranians, Miniature Poodles): luxating patella

Large and giant breeds (Great Danes, Rottweilers): osteosarcoma (bone cancer) in middle-aged and older dogs - sudden lameness in these breeds without obvious injury warrants prompt assessment

Young large-breed dogs: panosteitis (growing pains) - shifting lameness that migrates between limbs, self-limiting but painful

Frequently Asked Questions

My dog limped this morning but seems fine now. Should I still go to the vet? Note it and monitor. A single brief episode that completely resolves may be nothing - a cramp, a minor strain that sorted itself. If it happens again, or if it was severe even briefly, it's worth a vet visit. Having a log entry with the date and description means you can say "this is the second time in three weeks" if it recurs.

How do I tell which leg a dog is favouring? Watch your dog trot (not walk) on a firm surface and look at the head. Dogs instinctively shift their weight off a painful front limb by raising their head when that foot hits the ground and lowering it when the good foot hits. For back legs, watch the hips - the hip drops lower on the side of the sound leg.

My vet says the dog is fine and I'm worried. What should I do? If you have a clear description of what you observed - date, pattern, which leg, when it's worse - present that. A dog who's walked normally into the consulting room isn't necessarily fine; they may have warmed out of it, or the adrenaline of the vet visit is masking pain. Your detailed log is the clinical history the vet doesn't have access to unless you provide it.

Can limping in dogs resolve on its own? Minor strains and soft tissue injuries often do. Paw injuries generally do once the source is removed. Structural joint conditions don't resolve on their own but may have periods of improvement. Any lameness that persists for more than 48 hours, worsens, or recurs should be assessed.
